Activating the floorwashing function on Xiaomi devices is often an unobvious task for new owners, especially given the variety of models and software versions. Many users mistakenly believe that it is enough to install a water tank, but the smart home system requires a deeper setup to work correctly. Without the right configuration, the robot can ignore the command or, worse, damage carpeting unless virtual restrictions are set.
In this article, we will take a closer look at all the steps in preparing a smart vacuum cleaner for wet cleaning, from the physical installation of the module to fine-tuning the algorithms in the application. You will learn how to avoid the typical errors that lead to divorces or inefficient water consumption. Understanding the logic of Mi Home will allow you to use the device at full capacity, ensuring the perfect cleanliness of the floors.
It’s worth noting that the app interface may vary slightly depending on the region of the device’s binding and the firmware version. However, the basic principles remain the same for the entire Xiaomi and Roborock ecosystem. We’ll look at the universal steps that will suit most current models, including the Vacuum Mop series and the S-series.
Physical training and installation of the module
The first and most important step is to properly install the water tank. Unlike dry dust containers, the wet cleaning module has a specific design with valves. Be sure to remove the dry dust collector before installation, since the two modes as standard are structurally impossible for most budget and medium-sized models.
When installing a water tank, you need to wait for a characteristic click or an audible signal to confirm that the contacts are connected correctly. If the robot vacuum cleaner does not emit a greeting sound or an error indicator is on the display, try to remove and insert the module again, making sure that it is not skewed.
⚠️ Warning: Never attempt to start a wet cleaning if the module contains ordinary tap water without prior filtration. Using hard water will lead to rapid scale formation in the pump and clogging of the micropores of the rag, which will irreversibly damage the device.
For system durability, it is recommended to use distilled water or water that has passed through a reverse osmosis filter. This is especially critical for models with electronic water control, where the channels are microscopic in diameter. Regular maintenance and washing of the tank with clean water after each use will prolong the life of the pump.
☑️ Preparation of the wet cleaning module
Setting up the Mi Home application and selecting the mode
After you physically install the module, you need to go to the software part. Open the Mi Home app on your smartphone and select your robot vacuum cleaner card. On the main control screen, you will see several cleaning options; to activate the wash, you need to select a mode marked with the corresponding drop icon or the inscription "Mop".
In some versions of the interface, switching between Vacuum Only, Mop Only and Vacuum + Mop modes is done through a separate cleaning settings menu. If you want the robot to vacuum and wash the floor at the same time, make sure that the combined mode is chosen. However, for highly contaminated carpets, it is better to use vacuum cleaning mode only to avoid wetting the pile.
The important parameter is the water level adjustment. In the settings menu, you can choose from three levels: low, medium or high. For laminate and parquet, it is recommended to choose the minimum level to avoid swelling of the seams, while for ceramic tiles you can set the maximum supply for better cleaning of contaminants.
Don't forget to check the status of consumables in the app. The smart home system tracks the approximate life of the rag and filter, reminding you to replace them. Ignoring these notifications can lead to a decrease in cleaning quality and unpleasant smell in the room.
Creating a map and virtual restrictions
Effective wet cleaning is impossible without a pre-constructed map of the room, the robot needs to know exactly where the walls, the furniture and, most importantly, where the carpets are located. If the map has not been created, start the device in mapping mode, allowing it to travel around the entire available area without obstacles.
Once you save the map, go to edit mode and use Virtual Walls or Zones of No-Walls, which is a critical step, because even a minimal amount of water can spoil natural carpets or electric warm floors that are not designed to come into contact with moisture.
For advanced models with Automatic Brush or Carpet Boost, the system recognizes the fluffy surfaces and either bypasses them or enhances suction. However, relying on automation alone is risky, so manually checking the map for zoning is a must.
| Type of surface type | Recommended treatment | Water level | Limitations |
|---|---|---|---|
| Ceramic tile | Vacuum + Mop | High-pitched | No. |
| laminate | Only Morp. | Low. | Avoid stitches |
| parquetboard | Only Morp. | Minimum | Strict control |
| linoleum | Vacuum + Mop | Medium. | No. |
Using virtual walls is also relevant for areas with a lot of wires or fragile objects on the floor.The robot will perceive these boundaries as insurmountable physical obstacles, which ensures the safety of your belongings while autonomous.
What to do if a robot is stuck in a prohibited area?
Technical features of the pump operation
At the heart of the wet cleaning system is a miniature pump that doses water onto the cloth. Unlike the granular systems of the older models, modern Xiaomi devices use electronic control, which allows you to precisely control the moisture of the surface. The pump is activated only while driving, preventing puddles from forming on the parking lot.
The speed of the robot's movement directly affects the amount of water it delivers, and when you're slow in Careful Cleaning, the water flow increases, which allows you to wipe away the dried spots better, and when you're fast, you get more energy to get the surface dry.
⚠️ Warning: If you notice that the robot leaves puddles behind it or, conversely, drives on the dry floor, check the integrity of the silicone seals in the tank.
Regular cleaning of the pump outlet from scale is a mandatory procedure, which can be done using special cleaning solutions or weak citric acid, running them through the system in idle mode (without collecting dust), which will help to keep the performance of the device at a high level.
Selection and care of microfiber nozzle
The quality of wet cleaning is 80% dependent on the condition of the cloth. Standard microfiber wipes effectively collect fine dust and trap dirt, but require proper care. After each use, remove the platform with the cloth and thoroughly rinse it under running water without the use of aggressive detergents.
Drying the microfiber should be spread out, away from direct sunlight and heating devices. High temperatures can damage the structure of the fibers, which will make the cloth hard and will not absorb water properly. In addition, the dried fabric can scratch the glossy surfaces of the floor.
Replace the nozzle is recommended every 2-3 months of active use, even if it looks visually intact. Over time, the pile of microfibers wears off and loses its absorbent properties, turning into a regular rag that simply smears dirt on the floor.
💡
To enhance the effect of washing, you can use special concentrates for robot vacuum cleaners, adding them to the water. Conventional household products with foam can not be used categorically - the foam can disable the pump and sensors.
Typical problems and ways to solve them
One of the common problems is to report an error, "Water tank not installed" or "Check tank" even when the tank is physically in place. This is often due to oxidation of contact areas on the robot body or the tank itself.
Another common situation is that the robot ignores wash commands in certain areas, which may be due to the fact that the room settings prohibit wet cleaning for this type of coating. Check the settings of the rooms in the Mi Home app and make sure that the selected rooms are allowed Mop mode.
If the water supply seems to be insufficient, try to increase the value in the settings or check the filter at the outlet of the tank. Sometimes the air stopper in the system interferes with the normal circulation of water; a few light taps on the tank during operation can help eliminate suffocation.
💡
Regular maintenance of contact groups and timely replacement of consumables (rags, filters) are the key to the stable operation of the wet cleaning system throughout the life of the device.
